WHAT would you get if “The Blair Witch Project” had a baby with “Survivor?” Answer: “Murder in Small Town X,” Fox’s new show which premieres tonight.

It’s a game-reality show, which uses real people and actors. The real people solve a crime, and get to throw each other into the hands of the murderer. Or something.

We see the murders on the premiere, “Blair Witch”-style, and then supposedly the 10 real people (if you believe that 10 good-looking people who bring an incredible fashion sense to a fake murder can be called real) come to town to solve the murder.

There’s a real-life cop-also good looking – named Gary Fredo, who leads the 10 real people through the various clues, including the real killer’s weekly “killer’s game,” when the real killer sends a missive. If they guess right, one of the suspects is eliminated.

Then there is the whole town, which is made up of actors. Most of them are suspects, and everyone goes to the local bar and pretends to fight and the real people act like it’s real.

There’s also a house with blood-splattered walls and blood-soaked furniture, from which these 10 geniuses are supposed to get clues.

If that’s not enough, ineach episode they pull names from a box, and that person becomes “the lifeguard” which means that he can’t be thrown off that night. And he also gets to choose a patsy for the immunity challenge-rip-off. Whew!

There’s more: the real people also get to secretly vote for their own patsy. Therefore, two people get to be patsies. The two chosen ones are sent out by themselves in the dark, freezing night to bring back clues or be murdered.

No, this is not the ultimate reality show; the losers aren’t really killed, they are just thrown off the show. I was so confused at this point, I was ready to murder the producers.

Of course, like every bad sci-fi movie, the first person they throw to the wolves is the black person. Not only is she black, but she’s the only one who is – God forbid – in her 40s.

I don’t know if she and the blond in the sleeveless, belly-baring tight sweater, (good choice for a winter trip to Maine) – who is picked by the “lifeguard”- do get murdered, because Fox gave me the premiere without the final minutes.

This was a wise decision on their part too, because there would have been three deaths – including mine – since I was thinking that if I had to endure 10 more minutes I’d kill myself.

What this actually is, is a very expensive, and very complicated version of those mystery nights where people get all dressed up in different outfits and try to figure out whodunit.

Some of these real people (including one Ralph Lauren male model, another who claims to be a model but looks like she must model in strip clubs, the requisite bartender and the annoying guy with sticking up hair), are so dumb it’s hard to believe they can figure out how to open the door, let alone, whodunit.

So, why two guns? For one thing, when the two women get sent off by themselves in the dark of serted places, it gets good.

night to crawl around deAnd also because I like Shirley King, the African-American woman. She looks so out-of-place among these people who seem to dress for a living, that it’s ludicrous.

My favorite line? When Shirley, after being voted out to possibly be killed off says, “I’d rather face the killer than a back-stabber!”
